Replacing the battery in your Tesla fob is a relatively simple process that can be done at home with a few basic tools. However, it’s essential to note that the process may vary depending on the model of your Tesla and the type of fob you have. In this comprehensive guide, we’ll walk you through the steps to replace the battery in your Tesla fob, including the necessary tools and precautions to take.
The Tesla fob, also known as the key fob or remote keyless entry system, is a crucial component of your Tesla’s security system. It allows you to lock and unlock your car, as well as start the engine with the press of a button. However, like any electronic device, the fob’s battery can eventually run out, leaving you stranded without access to your car.
Replacing the battery in your Tesla fob is a cost-effective solution that can save you money in the long run. Instead of purchasing a new fob, which can cost upwards of $100, you can replace the battery for a fraction of the cost. Additionally, replacing the battery is a great way to extend the life of your fob and prevent it from becoming obsolete.
Before we dive into the steps to replace the battery, it’s essential to note that you’ll need to purchase a replacement battery specifically designed for your Tesla fob. You can find these batteries online or at a local auto parts store. Make sure to purchase a battery that matches the voltage and type specified in your fob’s documentation.
